Building a working MCP server is the easy part. Getting anyone to find it is the hard part. You can write a clean connector that reads your CRM, files your invoices, or answers questions from your own data, ship it, and then watch it sit in a GitHub repo that nobody opens. A registry listing is how a connector moves from private plumbing to something Claude and other MCP clients can surface to a user who is looking for exactly what you built.
At Automata AI in Sydney we build a lot of these connectors for Australian businesses, and the pattern is consistent. Teams spend weeks on the server and about ten minutes on the listing. That ratio is backwards. A discoverable connector that a client can suggest to a user is worth far more than a technically superior one that nobody can find.
What an MCP registry actually is
An MCP registry is a searchable index of connectors. When a user asks their AI client to do something the built-in tools cannot, the client can search a registry, find a matching server, and offer to install it. The registry stores the metadata that makes that match possible: the server name, a description, the tools it exposes, the install instructions, and the transport it speaks. It is the difference between a phone number written on a napkin and a listing in a directory people actually search.
There is a central open registry, and there are client-side catalogs that many AI products maintain on top of it. Submitting to the central registry is the base case. Getting picked up by the catalog a specific client shows to its users is where the real traffic comes from, so it is worth understanding both.
Why the listing is worth more than the code
A connector nobody can find is a private tool, not a product. The listing is what turns your work into distribution, and it does that quietly in the background:
A user searching for a Xero or HubSpot workflow can be shown your connector at the exact moment of need, with no marketing spend on your side.
A listed server carries a description and a tool schema, so the client can judge whether it fits before installing anything.
Registry presence is a trust signal. A maintained, documented entry reads as safer than a raw repository link pasted into a chat.
For a consultancy or a product team, a public listing is a portfolio piece that keeps working while you sleep.
We have seen a single well-placed connector listing drive more qualified enquiries than an $8,000 ad campaign, because the person who installs it has already self-selected as someone with the problem you solve. Distribution that pre-qualifies its own audience is rare, and a registry gives it to you for the cost of a good submission.
What a submission needs to pass review
Registries review entries for quality and safety before they surface them, and a sloppy submission is the most common reason a good server never gets seen. A review-ready entry has all of the following in place:
A clear, unique server name that reads as what it does, not a clever internal codename.
A one-line description that names the underlying service and the outcome, so search can match a real query to it.
An accurate tool list: every tool the server exposes, with honest descriptions and input schemas.
Working install instructions for each transport you support, tested from a clean machine and not just your own laptop.
A public repository or homepage a reviewer can open, with a licence and a README that explains setup.
Contact details and a maintenance signal, so the registry can tell the entry is not abandoned.
Getting the metadata right
The description and the tool schemas are what search indexes, so write them for the query, not for your brand. Name the service the connector talks to. A server called LedgerBot will never match a user typing Xero, but a server described as Xero invoice and contact access will. Every tool description is a chance to match another phrasing of the same need, so spend the words there rather than on adjectives.
If your connector touches customer records, say so plainly and note how it handles data. Australian businesses evaluating your server will ask about the Privacy Act before they install anything, and a listing that answers that question up front clears a real objection instead of leaving it for a nervous email later. State whether data leaves the user's environment, what the server logs, and which credentials it needs.
After you are listed
Treat the listing as living. When you add a tool, update the entry. When a client changes its install format, test yours again. A listing that fails on install is worse than no listing, because it burns the trust you spent real effort earning. Set a reminder to check your entry every quarter, the same way you would renew a domain, and version the server so users can see it is still maintained.
Getting discovered is a distribution problem wearing an engineering costume, and the server is the smaller half of the work. If you have built an MCP connector and want it in front of the people who need it, or you are weighing whether a custom connector is worth building at all, we are happy to talk it through.
